Swift v. Tyson (1842)

Erie Railroad Co. v. Tompkins, 304 U.S. 64 (1938), was a landmark U.S. Supreme Court decision in which the Court held that the United States does not have a general federal common law and that U.S. federal courts must apply state law, not federal law, to lawsuits between parties from different states that do not involve federal questions. In reaching this holding, the Court overturned almost a century of federal civil procedure case law, and established the foundation of the modern law of diversity jurisdiction.

Although the decision is not widely known among ordinary laypeople, most American lawyers and legal scholars regard Erie as one of the most important decisions in U.S. Supreme Court history.[1][2] The decision "goes to the heart" of the American system of federalism and the relationship between the U.S. federal government and the states.[1]
